DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the claims and equivalents thereof.

Embodiments of the present invention provide two-way venting for a container. In particular, embodiments provide two-way venting for a flexible pouch container. Referring to FIG. 1A, a side perspective view of a fitment 100 of one embodiment is illustrated. Fitment 100 includes a body 101 and a cap 110. The body 101 has a first end 103 and a second end 105. A body passage 106 passes through the body 101 from the first end 103 to the second end 105. Proximate the second end 105 of the body 101 the body passage 106 includes a lip 106 a. Proximate the first end 103 of the body 101 is a base 102. The cap 110 includes a first end 111 and a second end 113. A cap bore 110 c extends in the first end 111 of the cap 110, as illustrated. The cap 110 further includes a ridge 110 a proximate its second end 105. The ridge 110 a is designed to engage the lip 106 a in the body passage 106 of the body 101 when the cap 110 is selectively coupled to the body 101. This arrangement secures the cap 110 to the body 101 when the cap 110 is plugging the body passage 106 of the body 101. The cap 110 also includes a cap lip 110 b that is inside the bore 110 c. The cap lip 110 b is designed to selectively engage a connector as further described below. The cap 110 is coupled to the body 101 by opposed first retaining members 108 a and a second retaining member 108 b. The first retaining member 108 a and the second retaining member 108 b are made from a flexible material that allows the cap to move away from and towards the body passage 106 of the body 101. The cap 110 further includes a membrane 112 that extends between the cap bore 110 c and the second end 113 of the cap 110. FIG. 1B illustrates a close up view of the membrane 112 in the cap 110. The membrane 112 provides two-way ventilation 109 and 111 between the body passage 106 of the body 101 and the outside when the cap 110 plugs the body passage 106 of the body 101.

Referring to FIG. 2, a side view of fitment 100 is illustrated. In this view, the cap 110 is coupled to the body 101 of the fitment 100. In this arrangement, the cap 110 plugs the body passage 106 of the body 101 and the membrane 112 provides two-way venting into and out of the body passage 106. In FIG. 3, a side view of a container, which in this embodiment is a flexible pouch 114 including a fitment 100, is illustrated. The flexible pouch 114 has a seal 114 a around its outer perimeter. The body 101 of the fitment 100 includes a mid section 104 that is designed to be received in the seal 114 a of the pouch 114. Hence, the fitment 100 has a first section including the cap 110 that is sealed inside the pouch 114 and a second section including the base 102 of the body 101 being positioned outside the pouch 114. In FIG. 3, the cap 110 is engaged in the body passage 106. In this configuration the membrane 112 allows two-way ventilation out of and into the pouch 114 through the body passage 106 of the fitment 100.

FIGS. 4A-4C illustrate the manipulation of the cap 110 of the fitment 100 by a connector 120. In particular, FIG. 4A illustrates a connector 120 that is going to be inserted into the body passage 106 of the body 101 proximate the base 102 of the body 101. The connector 120 in this embodiment includes a connector passage 128 that passes from a first end 121 to proximate a second end 123. The connector passage 128, in this embodiment, terminates in a dispensing portion 126 that includes orifices 126 a and 126 b. The connector 120 includes a cap engaging portion 124 that is proximate the second end 123. The connector 120 further includes a mid-portion 125. The cap engaging portion 124 and the mid-portion 125 are received in the body passage 106 of the body 101 of the fitment 100 as illustrated in FIG. 4B. Cap engaging portion 124 further includes a cap connector recess 124 a that is designed to engage the cap lip 110 b in the cap bore 110 c of the cap 110. This arrangement couples the cap engaging portion 124 of the connector 120 in the cap bore 110 c of the cap 110. The connector 120 being pushed into the body passage 106 forces the cap 110 out of the body passage 106 of the body 101 of the fitment 100 as illustrated in FIG. 4B. This allows the orifices 126 a and 126 b of the dispensing portion 126 of the connector 120 to allow product to flow out of a container such as pouch 114 of FIG. 3. This arrangement would also allow product to be placed into a container in this configuration.

Once the product has been removed or put into the pouch 114, the connector 120 is removed from the fitment 100, as illustrated in FIG. 4C. Since the cap engaging portion 124 is coupled in the cap bore 110 c, the cap 110 is pulled into the base passage 106 of the body 101 of the fitment 100 thereby (once again) plugging the body passage 106 of the body 101 as the connector 120 is pulled from the body passage 106 of the fitment 100. Thus, in this embodiment the connector 120 selectively uncaps the cap 110 from the body 101 when the connector 120 is inserted in the body passage 106 of the body 101 to allow the product to be removed or added to the container. FIG. 4B illustrates a product flow 129 entering into the orifices 126 a and 126 b and a product flow 130 exiting the connector 120 when the cap 110 is removed from the body passage 106 of the body 101. Moreover, the connector further re-plugs the body passage 106 of the body 101 with the cap 110 when the connecter 120 is removed from the fitment 100. Accordingly, in this embodiment, the membrane 112 only provides two-way ventilation out of the pouch 114 when the cap 110 is plugging the body passage 106 of the body 101 of the fitment 100. FIGS. 4A though 4 c further illustrates a locking member 132 used to couple a product dispensing device (not shown) to the connector 120.

Referring to FIGS. 5A-5C, another embodiment of a fitment 200 is illustrated. In this embodiment the fitment includes a body base 201 and a cap 210. The body base has a first end 203, a second end 205 and a mid-portion 204. The mid-portion 204 is designed to be enclosed in a seal similar to the mid-portion 104 of fitment 100 sealed in pouch 114 of FIG. 3. The cap 210 of this fitment 200 is slidably coupled to the body 201. The cap 210 includes a membrane 212 that allows two-way ventilation when the cap is positioned to plug a body passage 206 of the body 201. The connector 220 in this embodiment includes a first end 221 and a second end 223. Proximate the second end 223 of the connector 220 is a cap engaging portion 224 that includes a cap recess 224 a that is designed to selectively engage the cap 210 similar to the engagement of cap engaging portion 124 and the cap 110 discussed in the previous embodiment. The connector 224 further has a mid-portion 225 and a connector passage 228. The connector passage 228 extends from the first end connect 221 to orifice 226 a that is proximate the cap engaging portion 224. As FIG. 5A illustrates the connector 220 in this embodiment is inserted in the body passage 206 in the body 201 of the fitment 200. FIG. 5B illustrates the mid-portion 225 and connecting portion 224 of the connector being inserted into the body passage 206 of the body 201 of the fitment 200. When fully inserted into the body passage 206, the connector 220 provides a product flow through orifice 226 and out through connector passage 228. Also, when connector 224 is fully inserted in the body passage 206 of the fitment 200, the cap 210 is manipulated into a non-plugging position such that fitment 212 no longer provides two-way ventilation between the body passage and the contents of the pouch.

FIG. 5C illustrates the connector 212 being removed from the body passage 206 of the fitment 200. The cap engaging portion 224 pulls the cap 210 down into the body passage 206 to plug the body passage 206 of the fitment 200 as the connector 220 is being removed, similar to the embodiment as discussed above. The connector 220 in this embodiment is illustrated as further including a rim 224 that abuts a base 220 of the body 201 of the fitment 200 when the connector 220 is received in the body passage 206. The connector 220 further includes a connector portion 220 proximate the first end 221 of the connector 220 and a locking member 232 that are used to couple a product dispensing device (not shown) to the connector 220.
